A lithium secondary battery having an electrolytic solution is provided. The lithium secondary battery of the present invention is a lithium secondary battery having at least a positive electrode, a negative electrode, and an electrolyte solution interposed between the positive electrode and the negative electrode, wherein the negative electrode is at least a negative electrode A current collector and a negative electrode active material layer, wherein the electrolytic solution contains an ionic liquid, and the negative electrode active material layer is interposed between a part or all of at least one side of the negative electrode current collector and the electrolytic solution. There is no intervening portion where the electrolyte solution, the negative electrode current collector, and the negative electrode active material layer are in contact with each other at the same time.
